The correct answer is "permissiveness".
Explanation:
The missing options of the question are:
permissiveness
synergistic effect
antagonism
additive effect
The correct answer is "permissiveness",
In biology, a permissive effect is defined as the effect that one hormone has enabling that a second hormone to exert its biological activity. Thyroid hormone has a permissive effect on the hormone epinephrine, by synthesizing ß adrenergic receptors, it enables the hormone epinephrine binds to them and cause the cells of the bronchioles to dilate.
Answer: C - Chromosomes create genes
Explanation: took the test 100%
Answer:
- 1/2 Aa Wx wx (colored seeds, normal starch)
- 1/2 aa Wx wx (colorless seed, normal starch).
Explanation:
- A (colored seed) is dominant over a (colorless)
- Wx (normal starch) is dominant over wx (waxy)
Both loci are independent.
A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).
- The homozygous recessive can only produce <em>a wx </em>gametes.
- The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>
<u>The possible offspring resulting from the combination of those gametes is:</u>
- 1/2 Aa Wx wx (colored seeds, normal starch)
- 1/2 aa Wx wx (colorless seed, normal starch).
Answer:
the first two and the last one are the most likely answers :)
